Program crash - problem with Tree Support

[rstoki]

Cura Version

5.6.0

Operating System

Windows 10

Printer

Creality Ender-3 S1 Pro

Name abnormal settings

Generate Support: True; Support Structure: Tree

Describe model location

The model is in the default location (in the center -- after Drag'n'Drop of STL file). The model is rotated 90 deg. counter-clockwise around green axis

Describe your model

Just a simple hook for cables created in Blender. It contains small (2.5mm) holes (cubical)

Cura 5.6 BUG-report.zip

How to reproduce:

• open Cura
• Drag-and-Drop the attached STL file
• rotate the model 90 deg. counter-clockwise (around green axis)
• turn "Generate Support": ON
• select "Support Structure: Tree
• Cura 'crashes' (probably an unhandled exception)

If the model is sliced without Supports => it works
If the model is sliced with Supports, and the Support Structure is set to "Normal", it works.
If the model is sliced without rotation => it works.

So the problem is probably with the Tree support structures, and maybe the combination of small holes.

We made some improvements to prevent slicing fails in Cura 5.7.0 available to download now. I was able to slice your model successfully in 5.7.0. Could you test if that's the case for you as well?
